Mexico's 'presidential vote-rigging' controversy continues

Mexico's post-election controversy continues. The next president is likely to be Enrique Peña Nieto, with 38% of the vote - this after half the ballots cast in this month's election were recounted. But leftist candidate Andres Manuel Lopez Obrador is refusing to concede defeat, gathering evidence that his adversary bought votes in the run-up to the election. He claims there were irregularities in three out of every four voting booths.
